Answer:

Step-by-step explanation:

The ENTIRE 360° arc length of the circle is the circumference

   pi d        ('d' is the diameter = 22 ft)

You want a 315° out of 360° fraction of this entire circumference

sooooo:

        315 /360 3.14 * 22 = 60.45 ft    (rounded)

Answer:

arc length ≈ 60.45 ft

Step-by-step explanation:

the length of the arc is calculated as

• length = circumference of circle × fraction of circle

length = 2πr × \(\frac{315}{360}\) ( r is the radius )

given r = 11 ft and using π ≈ 3.14

length = 2 × 3.14 × 11 × \(\frac{7}{8}\)

           ≈ \(\frac{2(3.14)(11)(7)}{8}\)

          ≈ \(\frac{483.56}{8}\)

          ≈ 60.45 ft ( to 2 decimal places )
